    Abstract: The present invention relates to an oscillating device, which comprises a driving module and an oscillating module. The driving module is used for producing a first driving voltage and a second driving voltage. The oscillating module comprises a first symmetric load circuit, a second symmetric load circuit, and a bias circuit. The first symmetric load circuit and the second symmetric load circuit produce a bias according to the first driving voltage. The bias circuit produces a bias current according to the second driving voltage. The oscillating module produces an oscillating signal according to the first driving voltage and the bias current, where the bias current is proportional to the bias. Thereby, by making the driving signal produced by driving module proportional to the bias of the oscillating module, simple compensation for temperature and process can be performed. Thereby, the frequency can be tuned using a few calibration bits.
